So I'm not sure I entirely understand your question but I'm aasuming you are asking why the distance is 0.8 and not 0.4? The answer is because the force F is a perpendicular distance of 0.8 from the pivot
You are correct actually I didn't realise I hadn't answered the last question, I calculated what the force would be without explain why it had to be that!
@@ifesjournal I believe the answer would be to state that forces up = forces down for an object in equilibrium, and therefore 1.6...x10^2 + 87.05... (from the previous calculation) = 249N for the forces up, and the forces down are 200N + 49N (from the first calculation), therefore forces are balanced, so the forces acting on the table allow 0 resultant force to be experienced by the tabletop.
Just realised now that these are the basic questions 😂
Brilliant explanation sir ...💛👼🔥👍
Thank u so much
How is second last question (b) o.8f isn't 0.4

you're a babe 👌✨
For the first queston I don't think it is meant to be -1 because anticlockwise torques are positive right? Correct me if I am wrong
You can define whichever direction you like as positive or negative, it shouldn't affect the end result.
Isnt the last question c an explain question? Rather than telling us to work out the reaction force?

@@burrowsphysics so what would the answer be?
